I receive a number of please-link-to-me requests each week. Some are for products, some are for random sites. I received one a couple of weeks ago and decided not to respond because I wasn't going to accept the link request. I received another request, this time with a please respond with an “aye or nay”. I replied “no.” I thought I was being helpful.
I received another email from the requestor telling me “We had sent you a business proposition. Your response to it is curt, rude, unprofessional and uncalled for. This “discussion” is over. Thank you for nothing.”
You betcha. Except now I remember the product's name and I will remember to tell people, if they ask me, whether they should do business with these people. Nope.
I certainly see how a negative one-word reply could be seen as curt. Except, they asked me for it! Oh well.
Do be careful about what you ask for. You might just get it.
